Abstract (en)

[origin: WO9113441A1] To obviate the use of supporting rods, an upper end piece of a coolant pipe (WR) penetrates the fuel element head (6) of a nuclear reactor fuel element and is supported on the fuel element head (6); the lower end piece (WRa) of the coolant pipe (WR) is fastened to, and supported by, the fuel element foot (HD), in particular with rods of partial lengths. The supporting skeleton therefore consists of foot and coolant pipe with spacers; the fuel element head and handle are placed on the skeleton and screwed onto the coolant pipe after the fuel rods are pushed into the meshes of the spacer support.
